MagnaFlow California Grade Direct-Fit Catalytic Converter for 2001-2005 Porsche 911 (3.6L) Front Left - 444066
$1,120.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2001-2005 Porsche 911 models including Carrera, GT2, GT3, Targa, and Turbo (3.6L).
The MagnaFlow California Grade Direct-Fit Catalytic Converter (444066) is engineered for precise fitment and emissions compliance on the front left side of your Porsche 911. Designed as a bolt-on replacement for the factory unit, this converter eliminates the need for cutting or welding during installation. It features a compact, low-mass spun body design with a single laser fusion weld to significantly reduce the risk of exhaust leaks while improving thermal efficiency.
Constructed for longevity in high-heat environments, the assembly uses 16-gauge 409 stainless steel mandrel-bent tubing to maintain OEM-like flow dynamics and fuel efficiency. The 410 stainless steel barbed hangers provide a secure mount that resists corrosion and dampens vibration. Each unit is CARB-compliant, making it legal for use in California and other states that follow California Air Resource Board standards.
- CARB Compliant (California Grade) for legal operation in restricted states
- Direct-fit replacement for the front left position; no cutting or welding required
- 16-gauge 409 stainless steel mandrel-bent tubing for optimal exhaust flow
- Durable 308 stainless steel MIG welds and 410 stainless steel hangers
- Includes gaskets and Torca AccuSeal exhaust clamps for a complete seal
- 3D scanned during development to ensure exact OE-style fitment
- Manufacturer Part Number: 444066
